Identification of Gait Disorders Using Fuzzy Expert System

Dr. M. Pushparani, B. Kalaivani

Abstract: Gait analysis is one of the emerging techniques in security aspects as well as clinical aspects. Clinical aspects mainly consists of reading gait signals with a view to diagnose the movement related diseases. This paper discusses about identifying the movement disorders with particular reference to Parkinsons disease and Huntingtons disease. It also attempts to differentiate between the above two apparently having similar disorders, so as to accurately diagnose the diseases. Mamdani fuzzy inference system is being used for diagnosing the diseases. Centroid method is used for defuzzification. This system gives better accuracy.
